Learn how you can connect Azure Data Lake Storage to Infragistics XamDataGrid to build dynamic grids.
Using Infragistics WPF UI controls, you can build contemporary applications reminiscent of Microsoft Office for both desktop and touch-based devices. When coupled with the CData ADO.NET Provider for Azure Data Lake Storage, you gain the capability to construct interactive grids, charts, and various other visual elements while directly accessing real-time data from Azure Data Lake Storage data. This article will guide you through the process of creating a dynamic grid within Visual Studio using the Infragistics XamDataGrid control.
You will need to install the Infragistics WPF UI components to continue. Download a free trial here: https://www.infragistics.com/products/wpf.
Create a WPF Project
Open VisualStudio and create a new WPF project.
Add a TextBox for passing a SQL query to the CData ADO.NET Provider and a Button for executing the query.
The XAML at this stage is as follows:
< Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:CDataXamDataGridGroupingListApp" xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf" x:Class="CDataXamDataGridGroupingListApp.MainWindow" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> < Grid> < TextBox x:Name="textBox" HorizontalAlignment="Left" Height="44" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="682" Margin="10,10,0,0"/> < Button x:Name="button" Content="Execute" HorizontalAlignment="Left" Margin="697,10,0,0" VerticalAlignment="Top" Width="85" Height="44"/> < /Grid> < /Window>
Add and Configure a XamDataGrid
After adding the initial controls, add a XamDataGrid to the App. The component will appear in the Visual Studio toolbox.
Arrange the component on the designer so that it is below the TextBox & Button and linked to the boundaries of the app.
Once the XamDataGrid is placed, edit the XAML to set the XamDataGrid DataSource attribute to "{Binding}" and set the FieldSettings AllowRecordFiltering and AllowSummaries attributes to "true." Next, add an empty method as the Click event handler for the Button component. The XAML at this stage is as follows:
< Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:CDataXamDataGridGroupingListApp" xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf" x:Class="CDataXamDataGridGroupingListApp.MainWindow" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> < Grid> < TextBox x:Name="textBox" HorizontalAlignment="Left" Height="44" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="682" Margin="10,10,0,0"/> < Button x:Name="button" Content="Execute" HorizontalAlignment="Left" Margin="697,10,0,0" VerticalAlignment="Top" Width="85" Click="Button_Click" Height="44"/> < igWPF:XamDataGrid Margin="10,59,10,10" DataSource="{Binding}"> < igWPF:XamDataGrid.FieldSettings> < igWPF:FieldSettings AllowSummaries="True" AllowRecordFiltering="True"/> < /igWPF:XamDataGrid.FieldSettings> < /igWPF:XamDataGrid> < /Grid> < /Window>
Connect to and Query Azure Data Lake Storage
The last step in building our WPG App with a dynamic DataGrid is connecting to and querying live Azure Data Lake Storage data. First add a reference to the CData ADO.NET Provider to the project (typically found in C:\Program Files\CData[product_name]\lib).
Next, add the Provider to the namespace, along with the standard Data library:
using System.Data.CData.ADLS; using System.Data;
Finally, add the code to connect to Azure Data Lake Storage and query using the text from the TextBox to the Click event handler.
Authenticating to a Gen 1 DataLakeStore Account
Gen 1 uses OAuth 2.0 in Azure AD for authentication.
For this, an Active Directory web application is required. You can create one as follows:
To authenticate against a Gen 1 DataLakeStore account, the following properties are required:
- Schema: Set this to ADLSGen1.
- Account: Set this to the name of the account.
- OAuthClientId: Set this to the application Id of the app you created.
- OAuthClientSecret: Set this to the key generated for the app you created.
- TenantId: Set this to the tenant Id. See the property for more information on how to acquire this.
- Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.
Authenticating to a Gen 2 DataLakeStore Account
To authenticate against a Gen 2 DataLakeStore account, the following properties are required:
- Schema: Set this to ADLSGen2.
- Account: Set this to the name of the account.
- FileSystem: Set this to the file system which will be used for this account.
- AccessKey: Set this to the access key which will be used to authenticate the calls to the API. See the property for more information on how to acquire this.
- Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.
private void Button_Click(object sender, RoutedEventArgs e) { //connecting to Azure Data Lake Storage string connString = "Schema=ADLSGen2;Account=myAccount;FileSystem=myFileSystem;AccessKey=myAccessKey;"; using (var conn = new ADLSConnection(connString)) { //using the query from the TextBox var dataAdapter = new ADLSDataAdapter(textBox.Text, conn); var table = new DataTable(); dataAdapter.Fill(table); //passing the DataRowCollection to the DataContext // for use in the XamDataGrid this.DataContext = table.Rows; } }
Run the Application
With the app fully configured, we are ready to display Azure Data Lake Storage data in our XamDataGrid. When you click "Execute," the app connects to Azure Data Lake Storage and submits the SQL query through the CData ADO.NET Provider.
Live Azure Data Lake Storage data is displayed in the grid.
Group the data by dragging and dropping a column name into the header.
As you add groupings and filters, the underlying SQL query is submitted directly to Azure Data Lake Storage, making it possible to drill down into live Azure Data Lake Storage data to find only the specific information you need.
